Application filed April 2t, 1917.- Serial No. lttvttl't.4

T o all whom 'it may concern Be it known that I, Cniiiinns W. Corien', a citizen ot the United States, residing at Canton, in the county ot Stark and State of' Ohio, have invented certain new, and useful lmprovenients in Automobile Attachments, 'ot which the following is a specification.

This invention has relation to improvements in motorvehicles, and has for an ob- 'iect to provide means therein for urging the vehicle 'forward when the driving Wheels are iio longer effective for that purpose, and the improvement includes a drum having a cable wound thereabout. one end of which is adapted io be connected to a stakedriven into the ground oiother relatively stationary object, and means operable by the engine of' ilu; vehicle for rotating the drum whereby the vehicle may be moved as above set forth. in addition to the foregoing my invention coinpi'ehends improvement in the details of construction and arrangement of the parts to be l'ieieinafter more fully described and particularly set iorth in the appended claims. lin the accompanying drawings in which; similar and corresponding parts are desig mated h v the same characters of reference iliroughout the several views in which they appear:

Figure t, 'is a vien7 in plan of the rear portion ot a chassis illustrating the embodiment therein of my invention.

Fig. 2, is a transverse section taken onjthe line ot the preceding tigure.

Fig. f5, is a longitudinal section taken on the line 3--3 oi Fig. 1, and

e. is a detail view taken on the line ci-Ll ot' Fig. 3.

lilith reference to the drawings 10 indicates the longitudinal traine members ot a motor truck of conventional design, 11 indi- Cates the rear axle, 12 the' rear driving wheels. and the differential. casing. The

vpiopeller shaft 14e which extends centrally and longiti'idinally7 ot the chassis and is associated at its rear end with the differential inechai'iism is provided at a point torward.v

ot the differential with a worin 15.

Transverse trame bars 16 are supported at opposite ends upon the longitudinal trame members of the chassis 'in longitudii'ia1w spaced relation, and longitudinally entending hanger brackets 17 are depended at their endsl trom said frame bars` 1G` saidhanger brackets being indicated at 17, a similar ianger bracket 18 is depended Yfrom the right hand chassis member 10.` Extending y transversely of the vehicle is a shaft 19 which is journaled in brackets 20 mounted upon the brackets' 17 and in a bearing 21 60 mounted upon the bracket 18. The shaft 19 carries a Worm wheel which is located be tween the brackets 17 for meshing engagement with the gear 15, said Worm wheel being furthermore formed upon its right hand tace with a clutch member 23. A collar or other suitable means may be provided whereby to prevent longitudinal movement ci' the worin wheel 22 upon the shaft, as said n orm Wheel is loosely mounted upon the 7o shaft and adapted for free rotation thereupon. A'second clutch member 24 is mounted upon the shaft and is adapted for engagenient with the clutch member 23 when moved into engagement therewith for that purpose. Said clutch member having a sleeve 25 4'termed concentrically thereupon adapted to embrace the shaft and is ixed'to said shaft i'or rotation therewith but adapted ior longitudinal sliding movement. A ratchet wheel :26 is termed with the sleeve 25 in spaced relation tothe clutch member 2t for va purpose which Will be presently nothd. A

pawl 27 is pivotally mounted upon one of the brackets 17 Yfor cngagementivith the 35 ratchet wheel 2G, said pawl is connected through the medium of a forwardly extending rod 28 with thcflorward end ot a shipijiei.'4 lever 29. Said shipper lever is extended longitudinally of the car andv provided l with a bit'urcated portion Il() at its rear end! which is adapted to straddle the sleeve 25 and` is dispi'ised between the ratchet wheel 26 and the clutch member Q4, the forward end ot said shipper lever being bent at right angles as indicated at 31 and pivotally mounted at the bend therein as indicated at 3Q upon the 'forward transverese bar 16. A doot pedal is mounted upon anypart of the chassis 'iframe tor movement about a tul- 10o criiin as indicated at 34. The upper end beine'-eiigagmililc by the toot oi" theI operator and toi' that purpose is extended through the li-oor ot' the car. The lower end of the foot pedal is then connected through the medium ot a rod `with the aforesaid end 31 of the shipper lever. It will be apparent that by oscillating the foot pedal, the pavvl 27 may he thrown into or out ot engagement With the associated ratchet wheel as the case may be. and it will be apparent that the shipper lever 29 will be oscillated in 'unison to shi-ft v'the clutch member 9A as well as the ratchet wheel 26 longitudinally upon their supporting shaft. The ratchet wheel 26 should be of a sucient width toperinit the pawl to engage therewith regardless of the position of the ratchet Wheel..

Mounted upon the shaft 19 is a drum 36 having anges 37 at either end and located preferably between one'r ot the brackets 17 and the adjacent bracket 18. 'lhe drum is keyed to the shaft for rotation therewith, and a cable 38 is provided having one end securedto the drum and the opposite end provided with a ring 39 which may be placed around a staker d0 driven into' the earth.

From the foregoing it will be obvious that in the event that amotor vehicle, truck or whatever machine the device may be applied to is stalled so that its driving wheels are inoperative for the purpose of producing further movement thereof, the free end of the cable 38 is att-ached to the stake e() mentioned above to a tree or other substantially stationary object, and the foot .pedal 33 pressed forward. As a result of this movement of the footped'al the clutch inember 24 will be thrown into engagement with the complementary clutch member 23, and it the engine of the vehicle is now set in motion, the motion of the propeller shaft 14 will. be transmitted `through the medium of the Worm and worm wheel 15 and 22 respectively, to the shaft 19 and consequently through the clutch member to the drum 36, As said drum rotates the cable will be wound thereupon,l and the vehicle will be' obviously drawn forward. lEaiinultaneously with the movement of the shipper lever, to throw the clutch members into engagement, the pawl 27 will be thrown out of engagement with the associated ratchet wheel whereby tepel'- mit such rotation ofthe drum as set forth above. A return of the foot pedal to former position will. again disengage the clutch members and throw the pawl into engage-- ment with its ratchet, whereby to retain the drum .against movement and consequently to retain the truck in any position to which ieee/,eci

it may have been advanced by the winding.' up ci the cable. The movement ol the truclz; may thus be accomplished gradually and by degrees without imparting undue srci upon the engine.

lVliile l have illustrated and descrilngd my invention with sonic degree of i(iirlicularit-y,

l realize that in practice various aller tun. thereover may be made, and .l ther tore desire to reserve the right and pri i f changing the form ot the details ol cons uction, or otherwise altering the arrangement of the corri-lated paris willlniut iiepai'liug from the spirit et the invention or the scopi; of the appended claim.

Having thus described my invention, what l claim as new and desire to secure by lietters Patent-isc ln a inotorvehicle, the combination willi `the propeller shaft of a worm incaintoil thereon, a. counter shaft journaled in the vehicle at right angles to the propeller shaft, a. worin 'wheel on said counter .shatt tor engagement with the worin of the propeller ,shaitt, a Clutch inenibor on said worin wheel, said worin wheel being loosely mounted on the counter shaft,.a second clutch member splined to the counter shait for engagement with the first clutch nieinlfer, a ratchet wheel mounted on said counter sli-att, a drinn mounted on said counter shalt a cable hai'- ing one terminal wound about the drinnv` :i bell crank mounted in the vehicle traine having one end engaging lthe second lclutch member to shift the suine, a paivl for ougagenient with the ratchet, a rod conii. i the pawl with the bell Crank, and foot pedal for operating the bell crank '\i.flu'-,icliy the clutch members may be brounjlit int engagement and the pawl siniultannously nioved out of engagement with its ratchet.

ln testimony whereof l atlix my signature in presence of two witnesses.
